Patent EP-0310312-A3 (EP)
IPC: C07H21/02
Filed: 1988-09-23
Abstract: A reagent which can couple with the 5′ hydroxy position 
of a nucleotide, typically the terminal nucleotide in a 
nucleotide multimer, under the same conditions used in known 
standard solid-phase nucleotide multimer synthesis. When so 
coupled, the reagent produces a substituted nucleotide multimer 
with a protected linking moiety which is deprotected under the 
same alkaline conditions typically used to deprotect nucleotide 
exocyclic amines of a completed synthetic nucleotide multimer. A 
single one of the class of reagents can be so coupled to any 
nucleotide, and since the reagents have a non-nucleotide 
skeleton, the resulting substituted nucleotide multimer does not 
have an additional nucleotide which could potentially interfere 
with hybridization with a target nucleotide sequence.

Title: Method of waste disposal involving oxidation of elemental phosphorus
IPC: A62D101/22
Filed: 1988-10-03
Abstract: A method of waste disposal is described which 
comprises initiating a zone of oxidation by combining a 
source of elemental phosphorus and an oxygen-containing gas, 
within a protective layer of an inert, non-flammable fluid 
(such as water). The non-flammable fluid protects the 
elemental phosphorus from otherwise contacting atmospheric 
oxygen so that the elemental phosphorus is oxidized within 
the protective layer by the oxygen-containing gas thereby 
providing a zone of high temperature oxidation to incinerate 
the waste (e.g., a chemical waste).

Patent EP-0326220-A3 (EP)
Title: Circuit arrangement for supplying a load
IPC: H02M1/00
Filed: 1989-01-24
Abstract: A circuit arrangement for feeding a load (3) from a low voltage energy source (1) via a direct-voltage conversion circuit (2). The direct-voltage conversion circuit periodically takes energy from the energy source by means of a main switching element (10) and supplies this energy as an increased supply voltage (at 12) to the load via an inductive element (9) and a rectifier (11). A starting switching element (15) takes energy for generating the supply voltage (at 12) from the energy source during a starting phase. The circuit arrangement is simple and compact and the energy losses produced are so low that it is economic to use it for energizing a small appliance particularly a small domestic appliance, from a battery or a rechargeable accumulator. A main control circuit (13) is supplied with energy directly from the supply voltage (at 12) and periodically controls the main switching element. A starting control circuit (16) is fed directly and exclusively from the energy source and periodically controls the starting switching element (15) so that is switching periods are shorter than those of the main switching. The starting control circuit, and thus the starting switching element, are switched off when the supply voltage reaches a predetermined value.

Patent EP-0329268-A3 (EP)
Title: Glass ionomer dental cement curable in two stages
IPC: C04B26/06
Filed: 1989-01-06
Abstract: A series of dual curing dental cements are disclosed which 
consist of powder and liquid components to be mixed within a 
preferred powder to liquid range by weight. Mixing is initiated 
immediately prior to usage following which the mixed material is 
applied to the tooth surface as required and cured within a few 
seconds by irradiation with high intensity visible light energy 
to a tough leathery consistency, thus permitting the bulk 
placement of other dental restoratives over it without 
disturbance. The second stage curing, which is chemically 
initiated, occurs much more slowly between the powder and the 
liquid and results in a fully set cement which is hard and rigid.  
     These cements are adhesive, both to prepared tooth structure 
and to composite dental restorative materials bulk placed over 
them. Thus, they combine the advantages of conventional dental 
glass ionomer cements with those of a first generation visible 
light cured cavity liner.

Patent EP-0386366-A3 (EP)
Title: Detecting and limiting electrical ground faults within electrical devices
IPC: G21D3/04
Filed: 1989-11-06
Abstract: An electrical ground fault detection and 
limitation system is used for example in a nuclear 
reactor utilizing a liquid metal coolant, e.g. 
sodium. Elongate electromagnetic pumps (80) 
submerged within the liquid metal coolant and 
support electrical equipment may experience an 
insulation breakdown occasioning the development 
of electrical ground fault current. Without some 
form of detection and control, these currents may 
build to damaging power levels to expose the pump 
drive components to the sodium with resultant 
undesirable secondary effects. Such electrical 
ground fault currents are detected and controlled 
through the employment of an isolated power input 
(120,128,124,122) to the pumps and with use of a 
ground fault control conductor (163,164) providing 
a direct return path from the affected components 
to the power source. The ground fault control 
conductor is additional to the electrical ground 
of the nuclear facility. By incorporating a 
resistance arrangement (160) with this ground 
fault control conductor, the amount of fault 
current permitted to flow may be regulated to the 
extent that the reactor may remain in operation 
until maintenance may be performed, notwithstanding 
the existence of the fault. Monitors such as 
synchronous demodulators may be employed to 
identify and evaluate fault currents for each 
phase of a polyphase power and control input to 
the submerged pump and associated support equipment.
Patent EP-0370777-A3 (EP)
Title: Method for processing digital text data
IPC: G06F17/27
Filed: 1989-11-21
Abstract: A text-editing system performs operations that result in text with correct punctuation at 
textual type boundaries. The system's processor executes a text editor, calling punctuator 
functions to provide appropriate fix-up data defining a sequence of operations to correct 
textual type punctuational structure. Fix-up data can be provided after a conventional 
manipulation operation, such as cut or paste in the cut-copy-paste paradigm, copy or move in 
the copy-move paradigm, or delete, in which case the defined sequence of operations corrects 
punctuational errors resulting from the manipulation operation. Fix-up data can also be 
provided to implement a higher level editing operation, such as changing the textual type of 
a textual type boundary. The punctuator provides appropriate fix-up data based on the 
operation currently being performed and on previously-obtained data about the current 
selection. The fix-up data include a starting point, a number of codes to delete, a list of codes 
to insert, a position to change capitalization, and how to change it. If the current selection is 
a text unit, the textual types and lengths of the textual type boundaries at each of its ends are 
used to obtain appropriate fix-up data. To enable the punctuator to obtain data about the 
current selection in advance of an operation that requires fix-up data, the text editor also calls 
the punctuator to handle requests to change the current selection. The punctuator does so by 
obtaining text codes in the regions surrounding the ends of the current selection. It tokenizes 
the text codes and performs pattern matching to find a textual type boundary, and saves data 
about the boundary, returning the end points of the new selection to the text editor.

Patent EP-0385174-A3 (EP)
IPC: B01D53/047
Filed: 1990-02-12
Abstract: An improved pressure swing adsorption process is disclosed for the 
recovery of two individual components from a multicomponent gas mixture. The 
process utilizes a first group of adsorbent beds selective for the secondary 
component product and a second group of beds selective for tertiary impurities 
in the mixture. The gas mixture is passed through the first and second beds 
in series and high purity primary component product is discharged from the 
second beds. The secondary component product is recovered by desorption from 
the first beds. Product recovery is improved by recycling depressurization 
gas from the first beds and by several novel pressure equalization steps. The 
process can be used to recover high-purity hydrogen and carbon dioxide from a 
gas mixture containing these components along with minor amounts of methane, 
carbon monoxide, and nitrogen.

Title: Temperature measurement in a slab mould
IPC: B22D11/22
Filed: 1992-05-18
Abstract: The invention relates to a method for controlling the taper of narrow faces, adjustable between wide faces, of a liquid-cooled plate mould for the production of continuous steel slabs. In order to specify a method for controlling the taper of narrow faces, adjustable between wide faces, of a liquid-cooled plate mould for the production of continuous steel slabs, it is proposed that the temperature of the cooling fluid at the coolant outlet of each of the liquid-cooled plates of a mould should first of all be measured, that a cooling surface-related specific temperature value be formed from the measured temperature, that the specific temperature values of opposite plates be compared, furthermore that a comparison of the temperature values of each plate with the specific temperature values of the adjoining plates be carried out and that, if there is a difference between the temperature values, an actuating value corresponding to the size of the difference be applied to the drive of that narrow face which delivers the lower temperature value to bring about an increase in the taper.
